EFFECT OF DATE OF GRAFTING ON SUCCESS PERCENTAGE AND GROWTH OF MANGO TRANSPLANTS

This study was carried out during the seasons of 2006 and 2007 to present the suitable date of grafting for Zebda, Fagriklan, Seedek, Ewais and Keitt mango cultivars onto Zebda rootstock in order to obtain a higher successful grafts of mango cultivars. Grafting mango cultivars with the cleft method especially on April produced a higher percent of successful grafts and gave highest scion growth with longer, thicker shoot and more number of leaves on the seedling than those taken in September. Furthermore, grafting both Zebda and Fagriklan on Zebda rootstock gave higher values of successful grafts and growth of the transplant than those obtained from grafting Seedek, Ewais and Keitt on the same rootstock. Whereas, Ewais and Keitt cultivars gave less vigorous grafts than that obtained from the other cultivars in the two dates of grafting.
